identify links in pdf with php

I want to create pictures out of a pdf. I know for linux there are free tools to do that. My problem is that I want to get links from a pdf file, identify them to use them later.开发者_高级运维 So I would need to know which they are and also on what coordinates on that page, in order to be able to use them.

Convert PDf to HTML eq "pdftohtml" and find href

Then with eq PHP dom get height of a href eq $('a').offset().top;
